GS4B031742GBT Description

The GS4B031742GBT from TT Electronics/IRC is a high-performance 7-resistor thin-film network designed for precision applications. Encased in a ceramic SOIC-8 package, it offers a 17.4KΩ resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic substrate enhances thermal and mechanical reliability.
